Title:
LED LIGHTING SYSTEM USING CONDUCTION ANGLE CONTROL-TYPE AND VOLTAGE VARIABLE-TYPE DIMMER FOR DIMMING LIGHT
Document Type and Number:
Japanese Patent JP2010198943
Kind Code:
A
Abstract:
To solve the following problem: the light of a LED lamp or the like cannot be so successfully dimmed as in that of an incandescent lamp by using a familiar triac type dimmer.
A constant current load circuit is connected to the output of the dimmer. The dimming voltage of the triac-type dimmer is not applied directly to a LED, but a current corresponding to the dimming voltage is carried into the LED.
